Use of earthworm species to biodegrade various substrates (industrial wastes, agricultural residues, etc.) for composting has proven to be successful after initial stabilization of vermi beds. This study presents optimization of vermi beds (soil + cowdung) for culturing of earthworms (Eisenia fetida, Eudrilus eugeniae, and Megascolex megascolex.). Optimum proportion of soil + cowdung (1:3) for ...

Keratinase producing bacterial strains were isolated from the chicken feather dumping site. Keratinase producing bacterial strains were identified by physical, biochemical characteristics, fatty acid methyl ester (FAME) and 16S rDNA sequences. Medium optimization of the selected keratinase producing bacterial strain (Bacillus thuringiensis TS2) was checked with various parameters such as incuba...

We discuss the optimization of a green-field beta beam in terms of baseline, boost factor, luminosity, and isotope pair used. We identify two qualitatively different cases: θ13 not discovered at the time a decision has to be made (θ13 small), and θ13 discovered at that time (θ13 large). For small θ13, it turns out that the obtainable sensitivity is essentially a matter of the effort one is will...

Invertase production by wild cultures of Saccharomyces cerevisiae isolated from dates available in local market is reported. Five hyperproducing yeast strains (>100 fold higher invertase activity) were kinetically analyzed for invertase production. Saccharomyces cerevisiae strain GCAII was found to be a better invertase yielding strain among all other isolates. The values of Qp and Yp/s for GCA...

in this study, modeling and optimization of coagulation and flocculation processes in cod removal of galvanized wastewater treatment plant of mobarakeh steel complex (msc) were studied. experiments of this study were designed using response surface method which is one of the most efficient methods in experimental design. the variables assessed in this study, are four factors including ph, input...

Most high throughput structural proteomics centers use the sitting-drop method to obtain diffracting crystals for three-dimensional (3D) structure determination of biological macromolecules by x-ray crystallography. Although several robotic systems are available for dispensing the initial sitting-drop screening conditions, generally they are not used for optimization of crystallization conditio...
